Twain Harte Creek Sewer Line Crossing Emergency Repair Project

Streambank erosion undermined and exposed a sewer line crossing at Twain Harte Creek very near Twain Harte Lake. Remove, replace, and extend existing concrete encasement; remove woody debris; and fill undermined voids and create cutoff wall to reduce risk of sewer line failure and sanitary sewer overflow before heavy writer rains increase risk. up to 9 cubic yards of concrete net fill may be used.
